clutch-closing key aforesaid, W'llfiilBVGl it desired, as the mere operation of the linespace lever effects the starting of the general operator. v v

' ll'ther features and advantageswill hereinatter appear.

in the accompanying drawings, Figure 1 is a fragmentary perspective View, showing the connection between the line-space lever and the means for controlling the operation of general operator. Fig. 2 is a detail VlCW partly in section, showing; the relation of the trip to the line-space lever. l? i ragi'nentary top plan View, showing the means actuated by the line-space lever to control the general operator of the coin; puting mechanism. Fig, l is a side View in 5 a spread perspective View, showingdetails or the trip Referring more particularly to the separate parts of this invention. embodied in e form shown in the drawings, 1 indicates the keys-of the typewriter which are secured hey lovers Q'and operate through the teiniediary of hell cranks 3, type bars i to swing the latter-upwardly and rearwardlyagainst the front side of a platen 5 mounted to rotate in bearings on a platen frame 6, which. 1n turn 1s mounted on a carriage T. The movement of the carriage may be con- -trolied in the usual manner common to the Underwood typcwriting machine at each actuation of a key by an escapeinentniechanisin indicated in general at 8;

The platen may be rotated in'the usual manner by hand by means of a knob 19; and

it is also rotated for the purpose 'otlinespacing. In the form shown, the platen is provided with a ratchet Wheel 10 engag'eable by a pawl 11 pivotally mounted on a sliding; plate 12. Pa'wl 11 is provided with a toe 13 which engages an adjustable rest 14 to vary extent of rotation of the platen by the par/h lhe platen isheld in any adjusted position by a spring-pressed detent The ilate 12 is normally heldin a forward )os1- 'tion by means of a spring 16, so that a right angle extcnsion'll thereon may be engaged bv a short arm 18 of a pivotally mounted lne-spaci-r lever 19. The arm 18 contacts with the extension 17 so that the platen and traine will be free to move up and down "tire to the line-space lever {for we of changing; from lower to characters without interru" (roam-action. alts the carriage 7 W p l 1 under the control of e, i cinent 8, one Ui 1l10l.' t'appets 29 provided thereon come suceesively into engagement filth a loi'jeulcs 21, so as to rock the '1 about nterincdiate pivots, whereby the rear thli 1st. links lhese thrust lino h 2? at their lower ends with linkages thereof are forced down to d press whereby denominational column bars E i are raised successively to correspond with the denominational columns of the Work sheet at the printing point. r

it Will be noted in passing that the link ages are of the transposing type'so that the acl: 21 at the extreme right of a group of jacks will actuate the column bar 24- at the ertren'ie left of a nest of column bars. Each of the column bars is provided with a series of nine settable pins 25 which do termine the subsequent extent of movement of the bars at. lVhenone ofthe column ha rs is raised, it brings its row of-pins above the rest of the pins in the nest, whereby one of the pins will be projected (town'- warf y below its fellows by one of a set of linkages 26 which are operated from the ill nuineral keys of the typewriter by stems E2? which engage projecting ari'ns 2e connected to associated linkages. The arrangement is ation of a numeral key will set a pin 25 corresponding thereto, thereby determining the extent of movement which a particular oar in elevation will subsequently have, according to the value of the numeral lrey struck.

Bars 2% are pmvided at their forward ends with racks engaging Wheels 76 connected to numeral-bearing dial or computing Wheels 7'?- Which will exhibit the -alculation run up by the niuneral keys through an aperture 78 in the casing 79. l /hen the numeral lreys have been'actuatml to Write a series of digits corresponding to units, tens, etc, of a number to be calculated, the valuation of said number Will have been concomitantly set on the nest of computing pins 25, so that certain of these pins, one

for each bar 52%, will project down below the bars into the path off a crossbar :29 on a general operator 30.

The general operator 30 is provided with a raclt bar 81 whereby it may be operated manually through the intermediary of a pinion 3% which meshes With the rack bar and which also meshes with the sector gear 33 rotatable by means of a hand crank 34. For many purposes, hOWGVQl', it prefer able to actuate the general operator 30 by means of a source of power such as. the lectrio motor 33. The connection between the electric motor 33 and the general operator, however, is preferably of such a type that motor 33 rotate independently of operation oi the machine, and only actuthe general operator 30 at such time as s 1 ecessary and then only for one complete of its movement. ihis connection may Jr of any suitable character, such as that lit shown and described in the application of .Al u rum wv the carriage and carry the computation, the line-space lever 19 can be thrown that it will rotate the platen, and before it reaches the limit of its throw, will have "rocked the trip -52 and snapped over the projecting arm .62 thereof, so that the ob structing pin 46 will have been raised from the path of the tooth 45 a suflicient time to permit the connectioil-controlling'element to spring forward and complete the operative driving connection between the motor and the general operator 30. The general operator reciprocates the column bars an extent according With the particular pins set, and these bars in turn rotate the dial or computing Wheels corresponding amounts. Even if the line space lever 19 should be held in its "actuated position, the spring 63 Will have returned the trip 52 to its normal position enabling the obstruction to to dis connect'the general operator from the motor after one complete cycle. The biparted form of the trip 52 enables the passive r turn ofthe line space lever 19.

Variations may be resorted to Within the scope of the invention, and portions of the improvements may be used Without others,
